Abstract
Description
(1)
where the xi's are standoff measurements made by the calipers R1, R2, R3 and R4 respectively, T is drill collar (tool) diameter, S1 is a simple caliper, Sx-axis a simple caliper in the x axis, Sy-axis is a simple caliper in the y axis. The acoustic sensor R1 is in the same azimuthal position as are the gamma ray detector assemblies shown in
Δρmin≦T1 (2).
If the test is not satisfied, data for the selected time interval have an excessive standoff and are not used. If the test is satisfied, other sectors in which the corrections Δρi are within a certain threshold of the minimum correction are identified. This may be denoted by identifying:
i:Δρ i ≦T 2·Δρmin (3).
The two threshold tests are depicted in
